That's dead posh, I don't even use a baking tray!Cleaning an oven is simple, and requires no hard work.
Simply get a spare baking tray, cover it with foil and put it at the bottom of the oven. Replace foil when needed. You will never need to clean the bottom of your oven again if you do this.
I just wait. My oven said "self cleaning" on the box. My gf says it's a pack of dirty lies, but I prefer to believe that elves visit in the dead of night to clean the thing :/
Astoundingly, its still working. I have no idea why. Perhaps the element is wired in two halves, I presumed it was wired as a single complete circuit.
Bollocks to it then. I'm not spending good money where its not needed!
You need a wife ffs.
